s'rovn on FURNACE ap lic tio filed ma 22, 1914. Serial No. 840,217;

To all whom it may concern:

.Beit known that I. FREDERICK S. SEY- I Momma citizen of the United States, and residing in Manchester, in the county ofDelaware and State of'Iowa, have invented a new-and Improved Stove or Furnace Feed, of which the following is a full, clear, and exact description.

An object of my invention is to provide an automatic coal feeder particularly adapted for feeding coal to small heating stoves, ranges, house boilers, tank heaters, feed cookers, and the like, in which there is 5 not a very large consumption of coal.

The'invention is designed to bebuilt with I the stove, range or furnace, in the manufacture of the latter, or; to be made up as aseparate attachment applicable to stoves, etc.,

' alreadymanufactured.

It is afurther, object of my invention to provide an automatic feed, the action of which may be regulated so that the period of operation will extend over any desired number ofhours.

"i It is also an objectiof my invention to ro,

vide for the feeding of a small quantity of *ucoal during'the early hours of the night only, or for the feeding of a given quantity of coal during only the later hours of the night or early morning.

"Further objects of my invention are to promoteeconomy in the consumption of fuel to minimize orentirely. obviate the produc tion of smoke and soot; to provide a feed that will result in an even the without the useol" a thermostat; to provide an attachment that will be effective with either hard or soft coal; to save labor in attending to the firing of a stove or furnace; to, promote cleanliness in lessening the dirt resulting from the burning of coal, particularly 'bituminous coal; and to prevent explosions in stoves due to the accumulations of explosive gases therein. I v

An object of the invention furthermore,

is to provide an automatic feed improved 7 in various particulars, to theend that efficiency of operation may be promoted as well as economy ofmanufacture and sim plicity of adjustment and control. 7 The invention will be particularly explained in the specific description following. T

Reference is to be had to the accompanying drawings forming part of this specification, in which similar characters of refer q ence indicate fragmentary 7 ,side

views. I I

' Figure l is'a longitudinal vertical section of an automatic feed embodying my invention, showing thesame in connection with a heating stove; Fig. 12 is a sectionalplan view on line 22 of Fig. 1 and Fig. 3 is a v elevation broken away, and others in section, of the escapement mechanism arranged as i in Fig. 1. i

Referring moreparticularly to Figs. 1 y and 2, a box-like coal magazine/10 is T mounted on top ofthe heating'stove A, said magazine being preferably oblong. The

with parts.

, Specification of LettersPatentu lP t t d p y 23 1916 corresponding parts in all the magazine may be secured'infany suitable manner to the top of the stove or heater,

-As here shown, the magazine isrsupxported at the front by a bracket 11, and at therearby a feed tube 12 constituting a feeding opening leading downwardly through the top of the stove,' from the mag azine. Extending downwardly below the feed tube 12 is a defiector13, to direct toward the center of the stove or heater, the

follower 15 is 7 provided and has guided longitudinal movement in the magazine by means of a longltudmal guiderod 16, which is fastened at itsends to the front and back i of the magazine and'passes througha transverse hole 17 in the follower 15 and also] 1 through a hole 18 in a depending lug 19 formed on a forwardly'extending arm 20 'on the follower.

The arrangement serves 4 to give a parallel guided movement tothe follower. Toadvance, the'follower, a chain 21 is connected with the same and extends in the present instance. over a sprocket wheel 22, the shaft '23 of which turns ina standard, 24; andbracket 24". Any suitable means maybe provided for exerting a pull on the chain 21. I haveshown a weight 25 hung on the free end of the'chain, said weight serving to advance the follower, subject to an escapement mechanism provided for the purpose. '1 ,r

The escapement mechanism comprises a spur gear 27 and a train of 'pinions 28, in suitable number and of a form and arrange ment of an ordinary clock train. A pendulum 29 arries an adjustable weight 30, provided with any suitable member. as at 31, which projects at the side toward the pendulum sullicieutly to engage in any one of a series of vertical slots 32. pallet 33 is actuated by the pendulum, in the well known manner of such devices, and engages an eseapement wheel 34- driven by the last pinion in the clock train.

To return the follower to the front of the magazine after a charge of coal has been fed to the furnace. and permit another supply of coal to be deposited on the bottom of the magazine in front of the follower, a chain 35 is connected with the follower and is secured to a winding drum 36. In the arrangement shown the drum is mounted on a shaft 37 suitably journaled in brackets 38 or equivalent members of the magazine. The shaft 37 is adapted to receive a detachable crauk handle in the well known manner, the handle being indicated by dotted lines at 39. To retard the action of the drum and prevent slack in the chains when the supply of coal has become. exhausted, a suitable brake may be provided for the drum. As here sl1own,a plate spring 40 is provided for the purpose.

In the arrangement shown in Fig. 1, the chain 21 passes downwardly from the sprocket 212 through the fine or stove pipe 41, the latter being provided with a guide tube 42 extending vertically therethrough for the passage of the chain downwardly to a connection with the suspended weight The construction provides a combined fuel feed tube 12 and stove pipe collar which enables me to apply the magazine and its feed devices .to stoves presenting no fire door on the side or front, of which stoves there are vast numbers; the lower end of the feed tube 12 will fit any of the usual stove pipe collars or like expedients on the top of the stoves in question and the lateral flue 41 serves to connect the usual stove pipe section to the feed tube 12.

By the described construction the magazine 10 may be substantially tilled with coal from the follower 15 to the feed tube 1Q,and the feed device may be started at any time. by swinging the pendulum, after which the feed will be, continuous, being gradual unno coal fed through the feed tube 12 until the follower will be advanced to a position I about central of its total path of travel and only a limited amount of coal placed in front of the follower so that the supply will be exhausted in the required period and no more will be fed during the remainder of the night. On the other hand, if the follower be returned to a position adjacent to the outer,

end of the magazine and only a limited quantity of coal be placed directly in front of the follower, then obviously there will be a period has elapsed suflicient to bring the front of the coal to the said opening. This coal will not be fed during the early part of the night, for instance, but only during the later hours of the night or the early moming. The speed of the feed may be regu, lated by raising or lowering the weight 30v on the pendulum 29.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent:

A fuel feed ineansfor stoves, furnaces and the like. comprising a magazine adapted to receive a supply of fuel on the bottom thereof and formed with a discharge outlet in the bottom near one end, a follower mova in said magazine toward and from the sa outlet, means for advancing the follower force the fuel to the outlet, and a. combine fuel feed tube and stove pipe collar connected at its upper end with the magazine at the outlet and adapted at its lower nd to connect with the stove, there being a lateral branch'on said feed tube between ithe upperand lower ends thereof to receiv e a stove pipe section.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

. FREDERICK SANFORD SEYMOUR.
